Just wanted to add to this in case others are browsing with the same question. Parsec is free and works great for basic editing. If you pay for the full version, you can get 10-bit and dual monitors which makes it somewhat usable for coloring. For a serious solution, it's worth checking out Teradici PCOIP or other lossless remote desktop software. PCOIP will require hardware and not be cheap, but will provide extremely accurate colors (sacrificing frame rate a little). This is going off recommendations from the colorist subreddit.
